My most reliable home automation devices are the Lutron Caseta. I've never had any problems, aside from changing the batteries on the shades. The Ikea stuff is decent now but wasn't so great 6 years ago. I still have the original tradfri hub. An annoyance with them is that because you want to be able to control them with a physical switch, a power-outage will result in them coming back on when the power returns, instead of remembering their last power setting. They may have fixed this since last I looked. I'm just using the hub for the smart blinds at the moment.
